Flowey: ...

Me: that's what I thought

Appearance

Flowey has the appearance of a conscious golden flower. His structure has a white androecium, six yellow petals, and a light-green stem. Flowey can contort his face to show various expressions and can mimic the faces and voices of other characters. He mimics Toriel and Asgore in some situations, as well as his old self at the end of the Genocide Route. He also mimics the protagonist's face before the Neutral Route's final battle.

Personality

Initially, Flowey operates under a facade of friendliness and politeness. He often greets the protagonist with southern slang, such as "Howdy!", calls himself "your best friend," and, like his father, appends polite words such as "gosh" and "golly" to the ends of his sentences. Whenever he drops this guise of friendliness, he often calls the protagonist an "idiot."

Flowey has a malevolent and cruel disposition, berating the protagonist for not following his "kill or be killed" philosophy. Despite this, he also criticizes the protagonist at the end of the if they killed any monster. He is manipulative, devious, and a cunning planner and subtle if the circumstances require it. He retains his memories between because he was once able to SAVE. He is also shown to be extremely cowardly, as he kills his former father to appease the protagonist in a vain attempt to save his own life in the Genocide Route's conclusion.

Attacks 

As a flower, Flowey uses only three attacks: a five-bullet spread that slightly hone in on the protagonist's SOUL, a large ring of bullets which surround the SOUL and cannot be dodged and a vertical row of bullets which come from the side of the Bullet Board, from outside it. This attack is only used before his battle as Asriel Dreemurr. He can speed up the spread although the limits of his attacks and speed are unknown. Getting hit by his five-bullet spread in his first encounter deals 19 damage per bullet whereas the unavoidable ring attack heals 19 HP regardless of whether it hits the protagonist. Before his battle as Asriel Dreemurr, the bullets deal 7 damage until 6 HP where it is 5. 

Flowey: are we done yet?

Me: yes you may go now *yells* hey frisk can you take Flowey outside?
